Indeed, price per sms is about 4 eurocent if you don't want to commit to an extra 10 euro's for 1000 messages or 50 euro's in total per month. Add that to the unlimited characters, groups, smileys, photo/video/audio inline attachments and Whatsapp is a nobrainer. Although people now do start to talk about alternatives like Telegram. Facebook is popular but (some) people are careful and don't like to put "I'm on holiday" messages on Facebook (and now Whatsapp).

You really get irritated by that? BTW, very funny to put a obfuscated "format c: (rm -rf / )" in your signature, I'm sure some company that get there system thrashed because some junior tried to paste it in a root shell could sue you for it.

Samba here too, share from linux or windows, every file is visible, transcoding is useless since even 3 year old phones run 1080p natively. You can still do some file manipulation from a tablet/laptop/phone to fix subs for example. You can delete stuff you watched. You have __security__ unlike UPNP/DLNA mediaservers where everybody you give access to your wifi or LAN gets to see all your media. 1080p on Mplayer with android tablet/phone runs like a charm on wifi with lightweight concrete walls and approx 5-10 meters distance in between.

Lets be honest, the easiest of stealing cars is that you get in and drive away. If smart electronics, big mechanical bars, armored doors and breaks are preventing you from this you can always and quite easily use a truck with winch or towbar. Sound alarms might work on your drive way but not on a busy parking when a professional looking tow truck is having its go at your car. GPS antenna's are easily jammed/cut or covered. Besides the 'hacking' of electronics there are many ways to drill holes for cable clipping, fuse pulling or apply voltage to powered windows and/or locks . High value objects that are out there will always be of interest to people that have low moral values.

I like mine "Automatic AC/Climate Control", I do override the fan speed otherwise it starts blowing very hard with a lot of noise when the temp difference is big the first 15 minutes. I also keep the AC switched off when temperature is below 24C/75F. Home temperatures are very hard to control, first off all you would actually need automatic valves in other rooms besides the living. Then this all needs to be "networked" e.g. main thermostat in living room currently can't tell the heating to go on and only go to bathroom. (I would like that in the mornings, don't care for warm living room).
